Far from hurting existing schools, new charter schools in New York City have actually helped their neighbors improve, according to a recent study.

The study’s surprising conclusion adds some hard data to a divisive debate: Do the privately operated yet publicly funded institutions sap resources and hurt traditional public schools? Or do they exert competitive pressure that lifts all boats?

The answer, at least in New York City, is that traditional public schools should want to be as close as possible to multiple charter schools, and ideally share a building with one.

The study finds that being closer to a charter school led to small increases in math and reading scores, boosts in reported student engagement and school safety, and fewer students being held back a grade. The test score gains increased slightly more in traditional public schools that are co-located with a charter.

Sarah Cordes, a professor at Temple University and the study’s author, suspects that her findings are the result of the competition stoked by charters.

“I think having that close a proximity might really get administrators to get their act together,” she said. “Part of it is just that it’s really hard to ignore a charter school in your building.”

The peer-reviewed study, set to be published in the journal Education Finance and Policy, is based on student-level data from nearly 900,000 third- through fifth-graders between 1996 and 2010. Cordes’s method takes advantage of the timing of when new charter schools opened to isolate their effect on nearby district schools, using performance before and after the charter opens.

A school within a half-mile of a charter school, for instance, saw significant bumps in math and reading scores—estimates that are boosted with greater numbers of nearby charter schools, and schools from “high-quality” charter networks such as Success Academy or KIPP.

Teachers reported higher academic expectations and “more respect and cleanliness” after a nearby charter school opened.

Test score bumps at traditional public schools were even more pronounced in cases where they occupied the same buildings as charter schools—an arrangement that has drawn intense criticism from many educators and parents, and which often forces the schools to share resources like cafeteria and gym space.

Cordes’s results are consistent with previous research from other districts, which have typically pointed to either neutral or slightly positive test score effects of charter schools on their neighbors.

The critics get something from the study, too: evidence that existing schools do lose some students when charters open nearby. When a charter was between one-half to one mile from a district school, for instance, the district school tended to lose roughly 16 general-education students. But Cordes concluded that the population changes weren’t big enough to influence test scores.

So why do the city’s charter schools boost their neighbors’ performance?

One reason, Cordes says, is that the charter sector is working as it was intended: creating pressure on administrators to improve the quality of their schools.

Based on survey data collected by the city, she found that parents reported significantly higher levels of student engagement, and those with children in co-located schools were less likely to describe their schools as unsafe. Teachers reported higher academic expectations and “more respect and cleanliness” after a nearby charter school opened.

Cordes also points to the budgetary effects of charter schools. Somewhat paradoxically, given charter critics’ arguments, competition from charter schools led to more average spending per student at traditional schools—between 2 percent for schools that are further away to 9 percent for co-located schools.

Though she did not look at whether decreases in enrollment had adverse effects on programming that wouldn’t be measured by reading and math test scores or survey data, Cordes said future research should look at whether enrollment drops lead to smaller class sizes, which have been shown to boost learning.

The revolutionary ideals of Black Panther’s profound and complex villain have been twisted into a desire for hegemony.

The following article contains major spoilers.

Black Panther is a love letter to people of African descent all over the world. Its actors, its costume design, its music, and countless other facets of the film are drawn from all over the continent and its diaspora, in a science-fiction celebration of the imaginary country of Wakanda, a high-tech utopia that is a fictive manifestation of African potential unfettered by slavery and colonialism.

But it is first and foremost an African American love letter, and as such it is consumed with The Void, the psychic and cultural wound caused by the Trans-Atlantic slave trade, the loss of life, culture, language, and history that could never be restored. It is the attempt to penetrate The Void that brought us Alex Haley’s Roots, that draws thousands of African Americans across the ocean to visit West Africa every year, that left me crumpled on the rocks outside the Door of No Return at Gorée Island’s slave house as I stared out over a horizon that my ancestors might have traversed once and forever. Because all they have was lost to The Void, I can never know who they were, and neither can anyone else.

“If you believe you are a citizen of the world, you are a citizen of nowhere. You don’t understand what citizenship means,” the British prime minister, Theresa May, declared in October 2016. Not long after, at his first postelection rally, Donald Trump asserted, “There is no global anthem. No global currency. No certificate of global citizenship. We pledge allegiance to one flag and that flag is the American flag.” And in Hungary, Prime Minister Viktor Orbán has increased his national-conservative party’s popularity with statements like “all the terrorists are basically migrants” and “the best migrant is the migrant who does not come.”

Citizenship and its varying legal definition has become one of the key battlegrounds of the 21st century, as nations attempt to stake out their power in a G-Zero, globalized world, one increasingly defined by transnational, borderless trade and liquid, virtual finance. In a climate of pervasive nationalism, jingoism, xenophobia, and ever-building resentment toward those who move, it’s tempting to think that doing so would become more difficult. But alongside the rise of populist, identitarian movements across the globe, identity itself is being virtualized, too. It no longer needs to be tied to place or nation to function in the global marketplace.

A week after 17 people were murdered in a mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida, teenagers across South Florida, in areas near Washington, D.C., and in other parts of the United States walked out of their classrooms to stage protests against the horror of school shootings and to advocate for gun law reforms.

A week after 17 people were murdered in a mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida, teenagers across South Florida, in areas near Washington, D.C., and in other parts of the United States walked out of their classrooms to stage protests against the horror of school shootings and to advocate for gun law reforms. Student survivors of the attack at Marjory Stoneman Douglas High School traveled to their state Capitol to attend a rally, meet with legislators, and urge them to do anything they can to make their lives safer. These teenagers are speaking clearly for themselves on social media, speaking loudly to the media, and they are speaking straight to those in power—challenging lawmakers to end the bloodshed with their “#NeverAgain” movement.

Deputy Attorney General Ron Rosenstein flew to Seattle for a press conference at which he announced little, but may have said a great deal.

Back in the fall of 2001, exactly one month after the 9/11 attacks, a lawyer in Seattle named Tom Wales was murdered as he worked alone at his home computer at night. Someone walked into the yard of Wales’s house in the Queen Anne Hill neighborhood of Seattle, careful to avoid sensors that would have set off flood lights in the yard, and fired several times through a basement window, hitting Wales as he sat at his desk. Wales survived long enough to make a call to 911 and died soon afterwards. He was 49, divorced, with two children in their 20s.

The crime was huge and dismaying news in Seattle, where Wales was a prominent, respected, and widely liked figure. As a young lawyer in the early 1980s he had left a potentially lucrative path with a New York law firm to come to Seattle and work as an assistant U.S. attorney, or federal prosecutor. That role, which he was still performing at the time of his death, mainly involved prosecuting fraud cases. In his off-duty hours, Wales had become a prominent gun-control advocate. From the time of his death onward, the circumstances of the killing—deliberate, planned, nothing like a robbery or a random tragedy—and the prominence of his official crime-fighting record and unofficial advocacy role led to widespread assumption that his death was a retaliatory “hit.” The Justice Department considers him the first and only U.S. prosecutor to have been killed in the line of duty.

The president’s son is selling luxury condos and making a foreign-policy speech.

Who does Donald Trump Jr. speak for?

Does the president’s son speak for the Trump Organization as he promotes luxury apartments in India? Does he speak for himself when he dines with investors in the projects? Does he speak for the Trump administration as he makes a foreign-policy speech in Mumbai on Friday?

“When these sons go around all over the world talking about, one, Trump business deals and, two, … apparently giving speeches on some United States government foreign policy, they are strongly suggesting a linkage between the two,” Richard Painter, President George W. Bush’s chief ethics lawyer who is a professor of law at the University of Minnesota, told me. “Somebody, somewhere is going to cross the line into suggesting a quid pro quo.”

On Tuesday, the district attorney in Durham, North Carolina, dismissed all remaining charges in the August case. What does that mean for the future of statues around the country?

DURHAM, N.C.—“Let me be clear, no one is getting away with what happened.”

That was Durham County Sheriff Mike Andrews’s warning on August 15, 2017. The day before, a protest had formed on the lawn outside the county offices in an old courthouse. In more or less broad daylight, some demonstrators had leaned a ladder against the plinth, reading, “In memory of the boys who wore the gray,” and looped a strap around it. Then the crowd pulled down the statue, and it crumpled cheaply on the grass. It was a brazen act, witnessed by dozens of people, some of them filming on cell phones.

Andrews was wrong. On Tuesday, a day after a judge dismissed charges against two defendants and acquitted a third, Durham County District Attorney Roger Echols announced the state was in effect surrendering, dismissing charges against six other defendants.

The path to its revival lies in self-sacrifice, and in placing collective interests ahead of the narrowly personal.

The death of liberalism constitutes the publishing world’s biggest mass funeral since the death of God half a century ago. Some authors, like conservative philosopher Patrick Deneen, of Why Liberalism Failed, have come to bury yesterday’s dogma. Others, like Edward Luce (The Retreat of Western Liberalism), Mark Lilla (The Once and Future Liberal), and Steven Levitsky and Daniel Ziblatt (How Democracies Die) come rather to praise. I’m in the latter group; the title-in-my-head of the book I’m now writing is What Was Liberalism.

But perhaps, like God, liberalism has been buried prematurely. Maybe the question that we should be asking is not what killed liberalism, but rather, what can we learn from liberalism’s long story of persistence—and how can we apply those insights in order to help liberalism write a new story for our own time.

Outside powers have been central to the nuclear crisis—but for a few peculiar weeks in February.

Of all the arguments in favor of allowing North Korea to leap into the spotlight with South Korea at the Winter Olympics—what with its deceptively smiley diplomats and even more smiley cheerleaders and the world’s most celebrated winless hockey team—one hasn’t received much attention. “It’s tragic that people of shared history, blood, language, and culture have been divided through geopolitics of the superpowers,” Talia Yoon, a resident of Seoul, toldThe New York Times when the paper asked South Koreans for their thoughts on the rapprochement between North and South Korea at the Olympics. “Neither Korea has ever been truly independent since the division.”

In this telling, having Korean athletes march under a unification flag at the Opening Ceremony and compete jointly in women’s hockey isn’t just about the practical goal of ensuring the Games aren’t disrupted by an act of North Korean aggression, or the loftier objective of seizing a rare opportunity for a diplomatic resolution to the escalating crisis over Kim Jong Un’s nuclear-weapons program. It’s also about Koreans—for a couple surreal weeks in February, at least—plucking some control over that crisis from the superpowers that have been so influential in shaping it over the past year.

A new study explores a strange paradox: In countries that empower women, they are less likely to choose math and science professions.

Though their numbers are growing, only 27 percent of all students taking the AP Computer Science exam in the United States are female. The gender gap only grows worse from there: Just 18 percent of American computer-science college degrees go to women. This is in the United States, where many college men proudly describe themselves as “male feminists” and girls are taught they can be anything they want to be.

Meanwhile, in Algeria, 41 percent of college graduates in the fields of science, technology, engineering, and math—or “STEM,” as it’s known—are female. There, employment discrimination against women is rife and women are often pressured to make amends with their abusive husbands.

According to a report I covered a few years ago, Jordan, Qatar, and the United Arab Emirates were the only three countries in which boys are significantly less likely to feel comfortable working on math problems than girls are. In all of the other nations surveyed, girls were more likely to say they feel “helpless while performing a math problem.”
